Technical Field

The utility model belongs to the technical field of alloy smelting, and particularly relates to a roller casting machine.

Background

In the traditional metallurgy industry, a fixed steel rail is used as a support, and a casting machine mold moves on the steel rail through rollers fixed at two ends. In the using process, lubricating oil is added between the roller and the shaft pin fixed in the middle. However, in the working process, the molten iron of the product can be adhered between the shaft pin and the roller, and dust can also enter a middle gap to cause the shaft pin and the roller to be fixed. The mould advances under the motor drive, because the running roller can't rotate, can only be at rail surface parallel motion, causes rail wearing and tearing, running roller wearing and tearing. The time is long, the shaft pin and the roller are worn, the roller is worn, the gap between the shaft pin and the roller is too large, the mold of the whole casting machine is asymmetrical, and the casting machine is easy to derail in the production process.

In the production process, if the casting machine has a derailment accident, the casting machine die does not move forwards along with the rotation of the motor and is in a stopped state. High-temperature nickel molten iron (or high-temperature molten iron of other alloy products) discharged by the submerged arc furnace flows down in a centralized manner at a casting opening, covers the mold, flows to a steel frame of a casting machine and the ground after overflowing the mold, and can cause serious safety production accidents.

Through two separation blades, dust and molten iron can be prevented from entering the roller through groove 11, and a bearing in the roller through groove 11 is protected.

The roller through groove 11 is internally provided with a bearing, and the bearing is positioned by a positioning snap ring 12 and is positioned in the roller through groove 11, and the roller 1 is connected with the shaft pin 2 through the bearing. The ball bearing is preferably adopted as the bearing, the circumferential outer wall of the ball bearing is clamped with the positioning clamping ring 12, and the middle part of the ball bearing is fixed with the shaft pin 2. During specific implementation, the roller 1 can be heated firstly, the roller 1 expands after being heated, then the bearing is arranged in the positioning snap ring 12, the roller 1 is cooled, and the bearing is firmly clamped by the positioning snap ring 12.
